day there are new stories about threats to the natural environment or actual damage to it, or about measures that have been taken to protect it The news is not always bad Areas of land are set aside for wildlife New forests are planted Steps are taken to reduce the pollution of air and water Behind all of these news stories are the scientists working to understand more about the natural world and through that understanding to protect it from avoidable harm The scientists include botanists, zoologists, ecologists, geologists, volcanologists, seismologists, geomorphologists, meteorologists, climatologists, oceanographers, and many more In their different ways all of them are environmental scientists The work of environmental scientists informs policy as well as providing news stories There are bodies of local, national, and international legislation aimed at protecting the environment and agencies charged with developing and implementing that legislation Environmental laws and regulations cover every activity that might affect the environment Consequently every company and every citizen needs to be aware of those rules that affect them There are very many books about the environment, environmental protection, and environmental science Discovering the Earth is different—it is a multivolume set for high school students that tells the stories of how scientists arrived at their present level of understanding In doing so, this set provides a background, a historical context, to the news reports Inevitably the stories that the books tell are incomplete It would be impossible to trace all of the events in the history of each branch of the environmental sciences and recount the lives of all the individual scientists who contributed to them Instead the books provide a series of snapshots in the form of brief accounts of particular discoveries and of the people who made them These stories explain the problem that had to be solved, the way it was approached, and, in some cases, the dead ends into which scientists were drawn ix 228 ATMOSPHERE thermoscope an instrument that shows changes in temperature by a visual effect, but that has no scale against which the magnitude of change can be measured thermosphere the region of the atmosphere that extends from the mesopause to the thermopause Torricelli vacuum a vacuum produced by filling with mercury a tube with one open end, immersing the open end in a bath of mercury, and allowing mercury to flow from the tube while keeping the open end submerged; the method was first used in by Evangelista Torricelli (–) torsion balance a device consisting of a horizontal bar suspended from a thin fiber that acts as a very weak spring; if weights are suspended from the ends of the bar the fiber will twist, causing the bar to rotate, and the amount of rotation is proportional to the force applied to the bar trade winds the prevailing winds in the Tropics, blowing from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere tropopause the upper boundary of the troposphere, at an average height of miles ( km) over the equator, seven miles ( km) in middle latitudes, and five miles ( km) over the poles troposphere the lowest layer of the atmosphere, extending from the surface to the tropopause upper atmosphere all of the atmosphere above the tropopause valley glacier a glacier that flows between walls of rock vapor pressure the partial pressure exerted by atmospheric water vapor Walker cell a flow of air over the Tropics in which air rises, moves east or west at high level, and subsides, feeding air into the trade winds Walker circulation the overall pattern of Walker cells warm cloud a cloud that contains only liquid water droplets warm front a front behind which the air is relatively warmer washout the removal from the air of particles that collide with and adhere to falling raindrops wet-bulb thermometer a thermometer with the bulb wrapped in a muslin wick to keep it permanently wet wind rose a diagram showing the frequency with which the wind blows from each direction at a particular location FURTHER RESOURCES
